This was my #1 feature request, so I posted a request to the forums. _ck_ posted a plugin to the forums - it worked right away, and didn't require any template tweaks. Fantastic :-).
What a relief this plugin has been. Before I installed this, we would get daily emails saying, "I never got my password emailed to me!" Now we never do, which is a huge relief. We still get emails about password resets not going through on email, but that's a problem with our email servers... not this plugin.
I'm excited for the "javascript checks of password for strength" feature that was mentioned as a potential future feature! But I figure it's better that a weak password that they can use, is better than a super strong password that they can't. The JavaScript check sounds like the perfect compromise.
Thanks for a great plugin :-).
